Availability:
DNS today has no protection against denial of service.
A sniffing attacker can disable all of your DNS lookups
by sending just a few forged packets per second.
DNSCurve very quickly recognizes and discards forged packets,
so attackers have much more trouble preventing DNS data from getting through.
Protection is also needed for SMTP, HTTP, HTTPS, etc.,
but protecting DNS is the first step.

Despite its extremely high level of security,
DNSCurve is very easy for software authors to implement,
and very easy for administrators to deploy.

DNSCurve is part of a larger project to encrypt and authenticate all Internet packets.
The techniques used in DNSCurve are easily adapted to other Internet protocols.
